I'm running Boinc Manager on several XP computers with multiple user accounts. I want to disable the "Run Manager at Login" on all users accounts. Every time a new users is created, it defaults to boot on start up. Any help would be greatly appreciated!

No easy way to do so. Either check it in the installer (3rd screen in, click Advanced, then take the check off of "Allow all users to control BOINC"), or in each user's BOINC Manager->Advanced view->Advanced->Options->uncheck "Run manager at login?"->OK, or you have to do it in the registry.

The above method is for BOINC versions up to 6.12, from 6.12 onwards it'll be BOINC Manager->Advanced view->Tools->Display and network options->uncheck "Run manager at login?"->OK.

When editing the registry, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Space Sciences Laboratory, U.C. Berkeley\BOINC Setup\ and change ENABLEUSEBYALLUSERS from whatever value it is now to nothing. Mind, there is a "boincmgr.exe /a /s" in a Run or RunOnce registry key, but removing that one will probably cause problems.

Now, do know that unless you installed BOINC as a service, BOINC will not run under other user-accounts when you remove the BOINC Manager start-up option. This starting of BOINC Manager runs BOINC. No manager startup, no BOINC. Unless you start it by batch-file, shortcut or script.
